Why not put the display table in its own jsp. Then you make an ajax call to that jsp and dump the html into your div.

This tag is in a jsp file. This is a snippet of my code: --------------------------- START OF FILE ------------------------- <% PortletRequest portletRequest = (PortletRequest) request.getAttribute("javax.portlet.request"); PortletSession renderPSession = portletRequest.getPortletSession(); ValueListHandler queryData = (ValueListHandler) renderPSession.getAttribute(GeneralPortalConstants.ATTRIBUTE__QUERY_DATA ); %> <script type="text/javascript"> <!-- setInterval("reloadList()", 5000); function reloadList(){ alert('RELOADING '); asynchGet('/reloadeventslistservlet'); showEventList(); } function showEventList(){ var div = document.getElementById("eventlistval"); div.innerHTML = ""; div.innerHTML = portletReq.responseText; } //--> </script> .... <c:set var="listaVal" value="<%= queryData.getList()%>"></c:set> <form name="listForm" method="post" action="${addRowURL}"> <input type="hidden" name="<%= GeneralPortalConstants.PARAMETER__CORE_EVENTLIST_EVENT_ID %>" value=""> <div id="eventlistval"> <display:table name="${listaVal}" id="item" pagesize="6" sort="list" style="width:100%; text-align:center" cellpadding="0" cellspacing="0" class="bem-theme.css"> <display:column sortable="true" property="eventId" title="${n:i18n('label.event.number')}" headerClass="sortable" /> <display:column sortable="true" property="startDateTime" title="${n:i18n('label.event.start_date')}" headerClass="sortable" /> <display:column sortable="true" property="coreEventType" title="${n:i18n('label.event.type')}" headerClass="sortable" /> <display:column sortable="true" property="coreEventSubType" title="${n:i18n('label.event.subtype')}" headerClass="sortable" /> <display:column sortable="true" property="coreEventState" title="${n:i18n('label.event.state')}" headerClass="sortable" /> <display:setProperty name="paging.banner.one_item_found" value=""></display:setProperty> <display:setProperty name="paging.banner.some_items_found" value=""></display:setProperty> <display:setProperty name="paging.banner.all_items_found" value=""></display:setProperty> </display:table> </div> </form> --------------------------- END OF FILE ------------------------- Now, I'm using Ajax to refresh my table asynchronously. The above jsp calls ReloadEventsListServlet class. In this class, I refresh the queryData variable, that contains a list of all the values. Now, I want to rebuild the table again. How can I do it? Here is my servlet: --------------------------- START OF FILE ------------------------- public class ReloadEventsListServlet extends HttpServlet { private final Logger log = Logger.getLogger(getClass().getName()); private List eventSubTypesVO = null; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); String eventTypeStr = ""; //(String) request.getAttribute(GeneralPortalConstants.PARAMETER__CORE_EVENT_TYPE_L IST) ; try { ValueListHandler valueListHandler = getManagerBem().doFilterCriteria(eventTypeStr); request.setAttribute(GeneralPortalConstants.ATTRIBUTE__QUERY_DATA, valueListHandler); } catch (BemException e) { log.error(GeneralPortalConstants.getExceptionMessage("BEM-ERROR", getClass().getName(), Thread.currentThread().getStackTrace()[2].getMethodName(), "getTaskListPage()"), e); e.printStackTrace(); } PrintWriter out = response.getWriter(); out.println("<display:table name='${listaVal}' id='item' pagesize='6' sort='list' style='width:100%; text-align:center' cellpadding='0' cellspacing='0' class='bem-theme.css'>"); out.println("<display:column sortable='true' property='eventId' title='${n:i18n('label.event.number')}' headerClass='sortable' />"); out.println("<display:column sortable='true' property='startDateTime' title='${n:i18n('label.event.start_date')}' headerClass='sortable' />"); out.println("<display:column sortable='true' property='coreEventType' title='${n:i18n('label.event.type')}' headerClass='sortable' />"); out.println("<display:column sortable='true' property='coreEventSubType' title='${n:i18n('label.event.subtype')}' headerClass='sortable' />"); out.println("<display:column sortable='true' property='coreEventState' title='${n:i18n('label.event.state')}' headerClass='sortable' />"); out.println("<display:setProperty name='paging.banner.one_item_found' value=''></display:setProperty>"); out.println("<display:setProperty name='paging.banner.some_items_found' value=''></display:setProperty>"); out.println("<display:setProperty name='paging.banner.all_items_found' value=''></display:setProperty>"); out.println("</display:table>"); } } --------------------------- END OF FILE ------------------------- The PrintWriter out doesn't work.
